.The invention relates in general to filled cloth, and more'particularly, to'a process for making fiber filled woven fabric from felted fibers andan open mesh cloth, According to the invention,a layer of papelr which may have been previously split, may be combined with Yan openmesh cloth by means of suitable 'adhesive Ito form a composite' web. The paper layer may be applied either to `one side of the cloth or to both sides, to Iform either a single composite web or a double composite web.

The composite web may then be suitablyl wetted by a wetting-mixture which may include waxes and sizing,- and then assed to a suitable calendaring machine w ere the felted paper is pressed thoroughly into the mesh of the cloth under suitable conditions of heat and pressure. The composite web, guyifrsingle, may have attached to the more pronounced paper side a suitable layer of attaching adhesive, and to the more prof nounced cloth side suitable finishing waxes may be applied. In the case of a` double z5 composite web attaching layers of adhesive,

may be applied to eitherlone or both sides,

or suitable layers of waxes or other calendaring materlal may vbe applied to yeither one or both sides.

Composite cloths according to the invention, find commercial use for shade cloths, book coverings, bags, tapes and many other articles. f Various lother features and advantages of the invention will be apparent from the following particulardescription and from an inspection of the accompanying drawings.

The invention'also consists in certain new and original features and combinations vof f 40 steps hereinafter set forth' and claimed.

Although the novel featureswhich are be- .lieved to `be characteristic of this invention will be pointed out with particularity in the l claims appended hereto, the invention itself, asl to its objects and advantages, the mode of its operation .and the manner of its oranization may be better understoodby refv erring to the following description'taken in connection with the accompanying drawings forming a part thereof, in wlnch Fig. l is a diagrammatic representation of aI single composite fabricrfof the invention before the paper layer has been forced into the cloth. l i

Figs. 2 and 3 represent, diagrammatically, the finished single and double composite fiber filled woven fabrics respectively; and Fig. 4 is a diagrammatic representation of apparatus used for performing the varioussteps in the process. A 60 In the following description and in the claims parts will be identied bypspecifcV names for convenience, .but they are intended` to be as generic in ytheir application to similar parts as the` art will permit.

Like reference characters denote like parts in the several figures of the drawin s. Referring now to the drawings (Flg. 1) ,1 a suitable'web 1 .of open mesh fabric, 'which may be light gray goods, may have suitably applied thereto a layer 2 of suitable adhesive material, such as an adhesive having a starch base, or any of the gums. A layer 3 of paper f which preferably has been previously split, may be applied to the adhesive and the paper web3 and cloth web l may be firmly pressed together lby passing between suitable rolls. The resulting composite web of cloth and paper denoted by 4 in Fig. 4, may then be` passed .through suitable wetting .\ro1ls 5, where awetting mixture 6 (Fig. 1) may be applied to the paper side of 'the composite lweb 4. In Fig. 4 the continuous line indicates the"paper web and the dotted line indicates the cloth web. -The wetting mixture may be water having suitable parts of waxes and sizt ing incorporated therewith. By means of y l the particular arrangement of wetting rollsv 5 shown in Fig. 4, the amount'of wetting mix- 4 A ture applied to the paper web maybe controlled very .nicely so that an infinitesimal l amount may be applied, if desired.-

The appearance of the composite web at I paper or cloth. The compromise web dar.

passed between these rolls, and is shown with the paper side facing the cast' iron rolls to prevent sticking.

The composite web is subjected to both heat and pressure in the calendar, and each part of the web 4 has positive contact with the rolls throughout the entire extent of the calendar from its introduction to its exit, to prevent shrinking. The ,composite web may be substantially dry when issues from the calen- V The wetting mixture may be applied hot, and, in any case, it spreads easily and soaks into the paper web 3 of thel composite Web. The rate of travel of the composite web 4 and the distance between the wetting' rolls 5 and super-calendar 8 is such as to allow suicient time for the wetting mixture to spread and properly saturate the composite web.

The wetting mixture impregnates the paper web, softens it, and the first rolls of the calendar 8 thoroughly press the homogeneous mass denoted by 11 in Fig. 2, of felted paper bers, adhesive, waxes and sizing into the open mesh of the cloth. The other rolls of the calendar dry and iron the composite webv while the homogeneous mass of paper, adhesive, waxes and sizing is in the open mesh of the fabric.

After the super-calendar, the composite web which is now a lled fabric, and denoted by 7 in Fig. 4, may pass between gumming l rolls 12 where gum or other adhesive 14 may be applied to the more pronounced paper side for attaching purposes, and further on the web may pass between waxing rolls 13 where suitable wax 15 may be applied to the more pronounced cloth side to give the proper nish.

It will be understood that the cloth used Y may be initially colored ordyed to any desired color, and also the paper may be initial- :y colored, if desired. The product may be suitably delivered and packed in sheet form, or may be wound up into bundle rolls.

In order to make the double composite web as shown in Fig. 3, an initial composite web of cloth 20 with layers of paper adhesively secured to both sides may be sub'ected to a similar process as above describe in connection with the single composite web, the

wetting mixture being applied to the paper` coatting on both sides of the double ycomposite we The wetting mixture softens the paper and adhesive and the homogeneous mass (denoted by 21 1n Fig. of softened paper, adhesive,

`waxes and sizing on both sides of the cloth web may be pressed into intimate relation with the cloth and into the interstices thereof. The paper bers on opposite sides of the cloth are pressed through the cloth vand 'contact and unite and interlock with each other to form a ber lled woven fabric. If desired, a sultable layer denoted at 22, of either prior articles of a similar nature, and has af much superior appearance. The surface is superior forprinting or embossing, and the cloth, when cut, does not unravel or curl at vthe cut edges.
